David Carr managed to get his QB rating to 75.4 this past Sunday with his team’s win over the New Orleans Saints. He was 10 of 17 for 119 yards, 1 TD, 1 interception and 1 sack. His complete QB rating for the year is 64.6. In the two games that he has started, he’s been a 54.4 and 75.4. “It was by far the worst pain I’ve ever felt in my life,” Carr said of a first-quarter sack by Will Smith that knocked him out of the game for several possessions. “I felt like I got sat on and then twisted. Every bone in my back popped all the way up to my neck. … I didn’t know, honestly, if I’d ever play again.” Carolina fans can only hope.
